A Generation Method of Harbor Ship Wave for Boussinesq-type Wave Transformation Model

摘要

In recent busy ports and harbors, their tranquility must be affected withnot only storm waves propagated from outside but also harbor wavesgenerated by inside ship navigation. In this study, a new generationmethod of ship waves is developed and installed to a Boussinesq-typewave transformation model, considering expandability of setting ofship navigation channels and applicability for general ship shape in aharbor. Through several sets of numerical simulations representing shipwaves measured in model experiments, a tuning parameter related tothe ratio of ship width and length to computational mesh size isintroduced for each approximation function of ship shape.
